MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was flagged by multiple heuristics as malicious, including a critical alert for linking to known malicious redirector infrastructure. The ML classifier also assigned a very high probability of maliciousness. The embedded URL, 'https://traffmen.ru/aws?utm_term=comptia+network+study+guide+exam+n10-+007', is the primary indicator of a phishing or redirection attempt, likely to deliver a secondary payload or lead to a credential harvesting page. No scripts were extracted, but the PDF structure and URL strongly suggest a phishing attack.

Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.

Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://traffmen.ru/aws?utm_term=comptia+network+study+guide+exam+n10-+007
